Answer:
This question is incomplete, the options are:
A) Decreased temperature
B) Strong southerly winds
C) Presence of a predator
D) Lack of water
The answer is C
Explanation:
A stimulus is something that provokes a response or reaction in a living organism. It can either be internal or external. An animal can respond to stimulus such as hunger, heat, predator etc.
However, among all the listed stimuli in the options, the PRESENCE OF A PREDATOR is most likely to result in a more rapid heartbeat in an animal. This is because the predator stimulus will require the animal to respond by running in order to survive. Running will increase its metabolic activity and cause its heartbeat to increase.
Answer:
Incomplete dominance
Explanation:
Incomplete dominance is the expression of phenotype of two paired alleles (i.e dominant and recessive allele) all together.
Usually when two alleles get paired, the characteristics of the dominant allele is expressed while the characteristics associated with recessive alleles are expressed only when the two recessive allele get paired.
Here in this case the characteristics of both type of allele are expressed i.e. both orange and purple strips appear in the offspring. Hence, this case shows the incomplete dominance.
Growth is defined as the irreversible increase in the dry mass of an organism. It is brought about by an increase in cell size or number. In plants, growth occurs throughout the lifetime of the plant. ... Plants have extensive powers of regeneration. They can replace lost or damaged tissue.
